How to Send Bulk SMS Safely and Effectively

To conduct an SMS Marketing campaign without violating mobile network regulations, you should apply the following techniques:

1. Increase Time Between Messages​

Instead of sending continuously, set a random delay of 1 to 10 minutes between each message. This helps:

  • Avoid exceeding the limit of messages sent in a short time
  • Make the sending process look more natural, similar to manual sending

Setting random delay between messages

2. Use Spintax Technique​

Spintax allows you to create multiple variations of the same content. For example:

{Hello|Hi|Hey} {sir/madam|valued customer}!

When sending, the system will randomly choose an option within each curly bracket, creating different messages such as:

  • "Hello sir/madam!"
  • "Hi valued customer!"
  • "Hey sir/madam!"

Example of Spintax usage

3. Personalize Content​

Use recipient information to create unique messages for each individual:

  • Add recipient's name: {{contact.name}}

Effective Message Template​

Here's an example of a message template combining all 3 techniques:

{{contact.name}}, {I hope|I trust} this message finds you well. {I was wondering|I wanted to ask} if your {company|organization} has {considered|looked into|explored} using {software|a solution|a software solution} for {marketing|sales|customer engagement} via {text messages|SMS|mobile messaging} {.|....|…|..|?|?!|!?} {?|?|?|?|?|?|||}

This template will generate thousands of different variations, helping to avoid sending duplicate messages and reducing the risk of being flagged as spam.
